APPARATUS FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 334,889, dated January 26, 1886. Application filed December 24, 1884: Renewed December 14,1885. Serial No. 185,664. (No modem T0 aZZ whom it may concern.-

Be it known that we, JOHN OGONNELL and FRANK E. WEEDEN, of the city and county of Providence, and State of Rhode Island, have invented a new and Improved Dyeing Apparatus, of which the following is a full, clear, and exact description.

The object of our invention is to dye, wash, oil, or dry under pressure and a continual stream of either liquor, air, or gas, wool in the fleece, card-balls, roving, and yarn, either in hank or in spools, cotton, flax, jute, or any other materials of a fibrous nature, including woven fabrics.

To that end ourinvention consistsin the construction and arrangement of parts, as will be hereinafter fully described and claimed. 7

Reference is to be had to the accompanying drawing, forming a part of this specification, wherein the apparatus is shown by a sectional elevation.

B is a tank of suitable size for containing the material to be operated on. O is a manhole therein, provided with a cover, whereby the tank can be closed tightly after the material is inserted.

D D are safety-valves; E,pressure-gages.; F, air-cocks; A, a steam-pump; J, liquor-tanks.

Kare the feed-pipes from tanks Jto the pump. L L are the discharge-pipes of the pumps, and M are drain-pipes on tank B. The dischargepipes of the pumps have the four connections 0 to tank B, so that the liquor or gas can be forced through the tank in four directions, and by conveying it back to the tanks J the circulation is kept up and theliquor or gas in the tank B kept under pressure sufficient to insure the complete and rapid saturation of the material for dyeing, scouring, or drying them.

In operating the apparatus the materials being first put in the tank and the latter then closed, the pump is then set in motion to force the liquor in. The air-cocks F are left open until the tank is filled, and the operation is then continued as long as necessary. The pressure will be indicated by the gases, and can be regulated according to the nature of the materials being operated on, and any excess will be relieved by the safety-valves.

To draw olt' the liquor from tank B, the drain-cocks M will be opened, unless it is desired to save the liquor, in which case it may be pumped out and back to tanks J through the connections K L.

This apparatus may be used for indigo dyeing with great advantage.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- 1. In an apparatus for dyeing, scouring,and drying fibrous materials,the combi:nation,with an operating-tank, of a supply-tank, a forcepump connected therewith, pipes leading from said pump into the upper and lower ends of the operating-tank, and branch return-pipes connected with the pipes leading to the operating-tanks and with the supply-tank, said return-pipes being provided with suitable valves, whereby the liquid or fluid may be forced into the material in the operating-tank from opposite directions, and then be forced back to the supply-tank, substantially as set JOHN OOONN ELL. FRANK E. WEEDEN.
